Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

This talk tells the story of symmetry in theoretical physics, and its interplay with developments in our understanding of gravity over the years. In this talk, McNamara explores the power of symmetry ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

The Andromeda Paradox exposes a troubling idea hidden inside Einstein’s relativity. It suggests that two observers, moving differently, may disagree on what events are happening right now — even ...

On 2 July, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose brightness varied rapidly during a routine sky survey. Its unusual signal ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Researchers at Oxford University and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) are ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

On July 2, 2025, the China-led Einstein Probe (EP) space telescope detected an exceptionally bright X-ray source whose ...
